Are you considering weight loss surgery? Istanbul, Turkey, has become a leading destination for medical tourism, offering high-quality obesity treatments like Gastric Sleeve surgery at competitive prices and with minimal waiting times. This comprehensive guide provides essential information for international patients looking to transform their health journey in Istanbul.

What is Gastric Sleeve?

Gastric sleeve surgery, or sleeve gastrectomy, is a widely performed bariatric / weight loss surgery. During this laparoscopic procedure, a significant portion of the stomach is removed, leaving a smaller, tube-shaped stomach. This reduction in stomach size not only limits food intake but also impacts hormones that control appetite, leading to substantial weight loss. Unlike some other bariatric procedures, gastric sleeve is a permanent and irreversible surgery.

Beyond weight reduction, gastric sleeve can significantly improve or resolve obesity-related health conditions such as type 2 diabetes, high blood pressure, sleep apnea, and high cholesterol. However, it's a major surgical intervention with potential risks and is not suitable for everyone.

Who is an Ideal Candidate for Gastric Sleeve Surgery?

Average Weight Loss with Gastric Sleeve

The suitability for gastric sleeve surgery is primarily determined by a patient's Body Mass Index (BMI) and overall health. While gastric sleeve offers significant benefits, it's not appropriate for all patients. Here’s a general guideline:

Who is an Ideal Candidate?
  • BMI of 40 or Higher: Individuals with a BMI of 40 or above are generally considered candidates for gastric sleeve surgery, even if they don't have accompanying health issues.
  • BMI of 35-39.9 with Co-morbidities: Patients with a BMI between 35 and 39.9 who also suffer from obesity-related health problems like type 2 diabetes, severe sleep apnea, or high blood pressure are typically good candidates.
  • Special Cases (BMI 30-35 with Uncontrolled Diabetes): In specific situations where type 2 diabetes cannot be controlled through diet and medication, patients with a BMI of 30-35 may be considered for metabolic surgery, which includes gastric sleeve, to manage their diabetes effectively.
It's crucial to understand that suitability is determined by a specialist after a thorough medical evaluation.
Who is NOT Suitable?
  • Active Severe Medical Conditions: Patients with active heart disease, advanced lung failure, or cancer.
  • Cognitive Impairment: Individuals who are not at a sufficient level of consciousness or understanding to comprehend the surgery, its risks, and the demanding post-operative lifestyle changes.
  • Severe Reflux: Patients with severe or uncontrolled gastroesophageal reflux disease (GERD) may be advised against gastric sleeve, as it can sometimes exacerbate reflux symptoms.
  • Non-Adherence to Lifestyle Changes: Patients unwilling or unable to commit to the essential gastric sleeve diet, gastric sleeve recovery time and lifestyle modifications required after surgery will not achieve lasting results.

Important Pre and Post-Surgery Notes:

  • Smoking & Alcohol: Patients must stop smoking and consuming alcohol at least 2 weeks before gastric sleeve surgery and refrain for several weeks/months afterward to ensure gastric sleeve recovery time and reduce complications.
  • Dietary Changes: A strict liquid diet is initiated post-surgery, gradually progressing to pureed and then solid foods. Significant, permanent changes to eating habits are essential.
  • Nutritional Support: Lifelong vitamin and mineral supplementation is typically required to prevent deficiencies.
  • Pregnancy: If planning pregnancy, it's generally recommended to wait 16-18 months after gastric sleeve surgery.

The Gastric Sleeve Procedure in Turkey

step 1

Initial Consulation

Your weight loss surgery journey in Istanbul typically begins with an online consultation. You'll provide your medical history, and your chosen surgeon will discuss the various surgical options, their benefits, risks, and post-operative care.

step 2

Treatment

Upon arrival in Istanbul, you'll undergo pre-operative tests, including blood work, and have a final consultation with your surgeon. The surgery is performed under general anesthesia and typically lasts 1 to 1.5 hours. Patients usually stay in the hospital for 3-4 nights for observation and initial recovery. During this time, your medical team will monitor your progress and provide initial guidance on aftercare.

Final Procedures

Before discharge, your doctor will give detailed instructions on diet progression, medication, vitamin supplements, and follow-up appointments. A final check-up and consultation usually take place a few days after leaving the hospital. For gastric sleeve, patients should plan for at least a 7-day stay in Istanbul.
